3. The apparatus of claim 1 , wherein the non-alignment assist image comprises a representation of a form to be completed using scanned targets existing on a surface prior to the projecting of the non-alignment assist image, wherein the scanned targets existing on the surface prior to the projecting of the non-alignment assist image have a first layout on the surface and wherein data locations of the form to be completed based upon a scanned targets have a second layout different than the first layout.

4. The apparatus of claim 3 , wherein the representation of the form has a first area and wherein the at least one projector is configured to indicate a second area of the representation of the form to be located over a scanned target, wherein the second area is smaller than and contained within the first area.

5. The apparatus of claim 1 , wherein the controller is configured to sequentially analyze a plurality of distinct portions of the image captured by the at least one sensor corresponding to distinct targets based upon positioning of the alignment assist image on the surface.

6. The apparatus of claim 1 , wherein the controller is configured to configure itself based at least in part upon an image captured by the at least one sensor.

7. The apparatus of claim 1 , wherein the at least one sensor comprises a two dimensional array of electromagnetic radiation detectors.

8. The apparatus of claim 1 , wherein the controller is configured to generate control signals directing the at least one sensor to capture an image of reflected electromagnetic radiation from the surface including at least one of the nonalignment assist image and the alignment assist image.

9. The apparatus of claim 1 , wherein the at least one projector comprises: a first projector configured to project electromagnetic radiation to form at least one of the alignment assist image and the non-alignment assist image; and a second projector configured to project electromagnetic radiation at the surface that is reflected and sensed by the least one sensor.

10. The apparatus of claim 1 , wherein the alignment assist image is configured to convey non-alignment information to a user.

11. The apparatus of claim 1 , wherein the alignment assist image comprises one or more alphanumeric symbols or characters.

12. A method comprising: projecting a non-alignment assist image onto a surface with a scanning device; and operating the scanning device based upon the projected non-alignment assist image, wherein the non-alignment assist image is a representation of an electronic form to be filled based upon scanned targets and wherein the method further comprises: positioning an area of the representation of the electronic form over a target on the surface; capturing an image of the target, and storing data based upon the captured image of the target in an area of the electronic form corresponding to the area of the representation of the electronic form; wherein the representation of the electronic form being projected has a first area and wherein the method further comprises projecting an indication of a second area of the representation of the form to be located over a target to be scanned, wherein the second area is smaller and contained within the first area.

13. The apparatus of claim 1 , wherein the one or more targets are different than the portion of the image analyzed.

14. The method of claim 12 , wherein the scanned targets have a first layout on the surface and wherein the form to be completed using scanned targets has a second layout different than the first layout.

15. A method comprising: projecting a non-alignment assist image onto a surface with a scanning device; and operating the scanning device based upon the projected non-alignment assist image, wherein the non-alignment assist image comprises a representation of a form to be completed using scanned targets; wherein the representation of the electronic form being projected has a first area and wherein the method further comprises projecting an indication of a second area of the representation of the form to be located over a target to be scanned, wherein the second area is smaller than and contained within the first area.

16. A method comprising: projecting a non-alignment assist image onto a surface with a scanning device; and operating the scanning device having a field of vision and based upon the projected non-alignment assist image, wherein the non-alignment assist image is an input request and wherein the method further comprises inputting a response in response to the input request, wherein inputting the response comprises locating an alignment assist image, having a predetermined position relationship to the field of vision on a target, wherein the input response corresponds to the target over which the alignment assist image was located during scanning.

17. The apparatus of claim 1 , wherein the scanned targets have a first layout and wherein the form to be completed based upon the scanned targets has a second layout different than the first layout.

18. The method of claim 15 , wherein the form to be completed using scanned targets includes a plurality of data locations, each data location to be filled based upon a different one of the scanned targets, and wherein the representation of the form includes a distinct representation for each of the plurality of data locations.
